Patented May 3, 1932 PATENT OFFICE GHARLEQ 11.. MQHZR. F WILMETTR, ILLINOIS SLUG- PBOLFILING" MACHINE Application filed October 13, 1930. Serial K0188389- This invention relates to improvementsin means and methods for producing type bars of peculiar and novel form and has special reference to a mechanism for re1noving parts of type slugs such as are produced on what is known as a Ludiow typograph machine. Such slugs usually have the type faces of greater height than the slug bar upon which they are formed, and by means :7 of this present invention, the overhanging parts can be easily and readily trimmed down or l'GlIlOVGCl. Sometimes it is desired to pro duce a printed line of this character with a more or less heavy printed line or line of '17 printing running through the letters from end to end of the line. In such a case, two oi the type bars are taken, the top portion-s of letters are removed on one bar, and the bottom portions are removed on another bar and then a rule or line of type is placed between these two bars when they are assembled in a type form.

A further feature is that the mechanism M embodying my invention can as readily be used to cut out tops of type bars for any pur pose desired, the vise which holds the type bar to be operated upon being capable of be ing set in different positions in relation to the cutter for holding the type bar in difi'erent positions relative to the cutter.

The invention contemplates the production of the type bars in the regular manner and then their cutting away orprofiling to produce the desired novel results.

55 The invention will be more readily under stood by reference to the accompanying drawings Forming part of this specification and in which Fi 1 is a fragmentary top plan view of a novel machine by which the method of producing novel printing forms may be best practiced;

In order that a clear idea of the invention may be quickly attained, it has been thought best to describe the product first.

In said drawings, Figs. 16 to 19, inclusive, particularly illustrate a printing member 30 in the form of a slug having .avery wide printing face 31 cast on or in conjunction with a relatively narrow bar 32, the type faces 31 overhanging the bar 32 on both sides.

The machine illustrated is capable of being,

operated to trim off one edge of the type face, as illustrated by the dotted lines 33, Fig. 16, for the purpose of making peculiar or novel display advertisements; in this instance, to permit the type bar 30 to be associated with a type rule 34 when set in a form for use.

As usually produced, such wide facetype faces have an edge portion 37 which extends above and below the actual type faces. It is desirable, in some instances, to set a rule 38 close to either the top or the bottom; of the type faces. For this purpose, the overhang is trimmed ofi' by means of the machine and, then a rule 38 can be set in the type form close to the printing faces. The printed result is shown in Fig. 25 when the heavy printed line 40 is shown close to the bottom of the letters 41.

It will be obvious that many other combinations can be produced, such, for instance, as a heavy line or a line of type inserted through the middle of a line of letters by trimming off the bottom parts of the type faces of one slug and the top parts of the type faces of a similar or duplicate slug, and placing a rule'between these two parts whenthey are assembled in a printing form.

Another very desirable result to be produced is the close association of type bars which have display letters of varying heights. Such a use is illustrated in Figs. 21 to 22, inclusive.

In this instance, two type bars, such as 42 and 43, are produced. These bars have as usual, the overhanging blank edge portions 37 and they have some letter faces which are wider than others. When it is desired to closely associate these type bars as indicated in Figs. 21 and 22, the overhanging edge portions can be trimmed away, as indicated by the dotted lines 44, Fig. 20 to provide notches,

etc., to receive the overhanging wider letters.

Fig. 22 shows the printed result of such cutting and close associating of the type bars 42 and 43. v

In Figs. 13 to 15, another important use of the machine is illustrated.

Some type bars 45 or keyboard slugmachine printing slug have blank spaces 46 between type faces'. 1 These blank spaces, as formed, are but-slightly below the level of the printing faces and, in some cases, in use such blanks may smudge the printed page. This necessitates the cutting down or notching of the upper edges of such slugs. This cutting down is shown by the full line 47, Figs. 15 and 16, the original top being shown by the dotted line 48, Fig. 14.

Another important use is to cut down or notch the tops of type slugs to permit the overhanging tops of other machine cast slugs to project over the slug. For instance, an adjacent slug might have a part adapted to project over and rest upon the surface 47.

The machine for producing these and other novel or desired results as illustrated in the drawings,consists of a frame having a base 50 and various upstanding brackets, lugs, etc, which support and carry the several working parts of the machine. The machine may be provided withyielding feet 51, if desired.

The working parts of the machine consist mainly of a vise mechanism 52 and a co-operating rotary cutter 53. The cutter 53 is prefera bly in the form of a circular milling cutter and is rigidly mounted on a horizontal rotatable shaft 54. The shaft is carried in upper ends of bearing standards 55 which may either be integral with the base 50 or secured thereto.

Between the standards, the shaft 54 carries a belt pulley ,56 which operatively connects the pulley with an electric motor 57 carried on a suitable extension 58. of the machine base 50.

The vlse mechanlsm 52 has a frame 59 formed at its lower part to provide two spaced ll apart bearings 60. which are mounted on a horizontal shaft 61. The shaft 61 is a' guide rod and is fixed at its ends in perforated projections 62 projecting up from the base 50.

The vise frame is adapted to slide back and on a plate member 66 which is pivotally mounted at its upper end on a horizontal shaft 67, which is rigidly mounted on the upper parts of the end plates 63 of the vise frame 59. as best shown in Fig. 5 The frame 66 is capable of being swung up and down on the shaft 67, the two limiting positions being indicated in Fig. 6, and also indicated, in refence to the cutter 53, in dotted lines in Figs. 3 and 4.

The plate 66 depends between the frame ends 63 and its middle lower portion is cut away, as best shown in Fig. 6 at 68, to provide pro-- jections 69 between which a vise plate member swing. The movable vise jaw 66 is secured upon the upper end of the vise plate 70 and is adapted to be swung in and out to clamp and loosen a type slug by a hand screw 7 2 secured in a threaded opening in the plate 66, and having a shoulder T3 for contact with the outer end of a holow projection "('4 on the outer side of the plate 68. lVithin the hollow outer end of a hollow projection *F-fl on the screw 72 to normally hold the two vise jaws separated i o the limit permitted by the screw TEL The rise as thus described is arranged parallel with tl c axis of rotation of the cutter 53; it is movable as a whole horizontally past the cutter; the jaws are capable of being set substantially vertically or horizontally or in any inti-n'niediary position as necessity demands, in relation to the cutter by swinging movement on the shaft 67 and the .ise mechanism can he swung, as a whole, from and toward the cutter on the lower shaft 54.

.Qhe vise frame 58 is provided at its lower with a rigid projection 76 for contact the base to limit the downward swinging movement of the frame.

As shown in Fig. 3, the vise is shown as set to present the overhanging edge portion 37 of a type slug 30 to the cutter to cut off more or less of said ed e, as shown in Figs. 16 to 18.

n) For this setting, the lower part of the vise 1 is swung inwardly on the shaft 67 to hold the type slug in substantially vertical position, as shown in full lines in Fig. 3. The vise is retained in such position by means of a clamping screw "l7 carried in a radial threaded opening; provided in boss 78, projecting outwardly from the lower end of the frame 66 and adapt-- cd to be screwed in to engage the outer edge T6 of one of the end plates 63 of the vise frame 59 and hold the frame 66 in relation to the frame 59. An adj stable stop 80 is an ranged in the main vise frame 59. This stop is in the form of a screw mounted in a threaded opening provided in the vise frame 59 and adapted to project toward the frame 66. The screw is held in its adjusted position by a jamb nut 61. This adustmcnt is for the p urpose of presenting the type slug to the out ter in such a relation that the slug); part 37 of the slug S6 is presented tangentially to the cutter, s best shown in dotted lines in Fi f .rlfter the screw stop has been once set, it does not need to be disturbed. When a slug is clamped in the vise jaws by the clamping screw 72 and the frame 66 is set against the stop 80 and clamped in such position by the clamping screw 77, the vise frarne 51 is then swung over toward the cutter. as shown in dotted lines in Fig. 3, to cut 0:65 the overhanging edge he type faces. The engage ment of the cutter teeth with the overhamn ing edge of the slug is controlled to prevent a too great engagement by means of a read ily adjustable stop mechanism. This stop mechanism consists of a horizontal stop bar 82 arranged on the inner side of the vise frame 59 and adjustable in relation to said frame to two positions, one for retaining the vise in a desired relation to the cutter for trimming off the edges of overhanging type faces, and the other for cutting down into the tops of type bars.

The stop bar 82 is mounted in notches 83 provided in the inner edges of the ends 63 of the frame 59' and is adapted to be yieldingly held inwardly by tension springs 8 each attached at one end to the ends 63 and at their other ends to the bar 82. The stop bar 82 is adapted to be set in its two positions by means of cam levers 85 at one end of the frame 63 and 86 at the opposite end of said frame. These levers are pivotally mounted on horizontal pivot screws 87 for the lever 85, and 88 for the lever 86. These pivots are arranged close to the stop bar 82. The pivoted ends of the cam levers are provided with two flat surfaces 89 and 90 for engagement with the stop bar 82 to set the bar in the two positions.

The levers 86 and 88 are adapted to bc swung on their pivots from one limiting, position to the other, by the swinging of the frame 64 from one of its limiting positions to the other. When the frame 64 is swung; down for cutting the overhanging type faces, the stop bar 82 is pushed out to its limit and when the frame 64 is swung up for cutting the tops of the type bars, the stop bar 82: is "drawn into the notches 83. This is accom plished by cross-head blocks 91 fixed on the ends of the frame 66 by screws 92, the free ends 93 of the cam levers being; bifurcated or slotted to straddle the cross heads. This sliding connection with the cam levers is provided to allow for theradial movement of the connection with the frame 66 and the levers on account of the different centers upon which they swing.

To limit the upward swinging of the frame 66 for setting the vise radial to the cutter 53, an adjustable stop 94 is arranged on one of the ends 63 of the frame 59 in the path of a projection 95 on one end of the frame 66. This stop 95 consists of a screw mounted in a threaded opening provided in a projection 96 on the inner side of one of the ends 63 of the frame 59,. and adapted to be secured in its adjustable position by a setscrew 97. hen the frame 66 is swung up againstthe stop 95, it is secured in such position by the clamping screw 7 7 which is forced in against the edge 98 of the adjacent end 63 of the frame 59. Said edge 98 is preferably curved in a radius struck from the center of the shaft 67 upon which the frame 66 swings so that the inner end of the clamping screw will not touch the end 63 as the frame 66 is swung up and down. The upper position of the frame is shown in dotted lines in Fig. 6 and in full lines and dotted lines in Fig. 4. As well illustrated in Fig. 4, when the frame 66 is too swung up, the slug which is carried by the Vise will be presented radially to the cutter 53 for the purpose of cutting notches in its upper edge, as illustrated in Figs. 13 and Besides the limiting of the swinging of the frame 66 to set the vise in the proper relation to the cutter for performing the two kinds of operations, it is necessary to limit the inward swinging of the vise mechanism to prevent the cutter taking too deep a out. For this purpose and for readily allowing the vise mechanism to be adjusted to carry the slug forward toward the cutter for successive cuts, a readily adjustable stop mechanism is provided.

This stop mechanism consists of a stop bar 99 mounted in a horizontal position transversely of the machine and provided with a longitudinally adjustable end 100 for contact with the longitudinal stop bar 82carried by the Vis-eframe 59.

The stop bar 99vis mounted in bearings 101 and 102 for horizontal movement toward and from the stop bar 82. The bar 99 is yieldingly held rearwardly by a coiled spring 103 mounted within the bearing 102 and arranged between .the head 104 'of'a screw 105 received in a threaded opening in the adjacent end 106 of the bar 99, and a shoulder 107 at the inner end of the bearing 102. Theadjustable end 100 of the bar consists of a screw adapted to be received in a threaded opening provided in the adjacent end 108 of the bar 99 and held in its adjusted position by a jamb nut 109;

The bar 99 is adapted to be forced toward the stop bar 82 against the action of the spring 103 by a vertical hand screw 110. This screw has a knurled handle 111 which stands at the top of the machine in a position to be readily grasped by the operator. The screw 110 is mounted in a threaded opening in a boss 112 on the frame. The lower end 113 of the screw 110 is rounded for contact with aflat arm 114. The arm 114 is fixed on the adjacent end of a rockrshaft 115 which is mounted horizontally in the frame of the machine below and at right angles to the stop bar 99. The end of the shaft 115 oppositeto the lever 114 carries a rigid slotted lever arm 116 which projects alongside of the stop 99. A pin 11'? is fixed in the stop bar 99 and projects into the slot 118 of the lever 116. The arrangement is such that when the screw 110 is screwed down, the stop bar 99 is adjusted toward the stop bar 82. Before swinging the vise to present a slug to the cutter, the screw 110 is preferably screwed down to force the stop bar 99 out far enough to cause the cutter to clear the extending shoulder of the face of the slug. Then, by backing off the screw 110, the vise with the slug can be gradually moved into contact with the cutter until a deep enough cut is attained then the vise mechanism is moved endwise on the guide shaft 46 to comtion to the frames 66 and 59 and in relation to the frame of the machine, it is necessary to provide a guide chute for the chips which will follow this bar.

The chip guard and guide consists of an open-topped chute 119 arranged beneath the cutter 53. The chute has a forward wall 120 which is rearwardly and downwardly inclined, the upper edge portion of which rests against the forward or inner face of the stop bar. The chute also has a rear wall 121 which is curved to one side to cause the chips to be thrown out to one side or end of the machine. The chip chute 119 is secured to and carried by a flat bar or plate 122 which is arranged in vertical position and adapted to move back and forth transversely of the ma chine. This plate is mounted for its movement on headed screws, the plate being provided with horizontal slots 123 to receive the screws beneath the heads. The plate is yieldingly held with the chute in contact with the stop bar 82' by a light tension spring 124.

The plate 122 has an upstanding projection 125 at its rear end to which the rear end of a cutter guard 126 is pivotally connected. The cutter guard 126 consists of a vertical plate 127 at the free end of which a curved cutter guard 128 is fixed. The guard proper 128 is adapted to lie in front of the cutter 53 at the time the operator is placing the slug in the vise, or removing it from the vise to prevent any possibility of the operators hand coming in contact with the cut ter which may be running at this time.

When the cutter is operating on a slug, it is lifted to a raised position out of the way because at this time there is no danger and the operator wants a clear view to observe just what he is doing.

The guard is lifted as the vise is swung in toward the cutter by means of a fixed camlning pin 129 on the frame of the machine upon which the lower edge 130 of the guard plate 127 rests, and by means of which the guard proper 128 is positioned vertically.

The lower edge 180 has an offset 131 which contacts with the pin 129 and raises the plate 127 and guard 128 as the stop bar 82 is moved into cutting position.

The two positions of the guard are illus trated in Fi s. 3 and 4, the lower or guarding position in full lines and the upper position in dotted lines.

The chute 119 is preferably enclosed within a bx-like structure 132 adapted to be secured to the base of the machine by a screw 133. The box 132 has an open outer end 134 and this is preferably provided with a chip deflector plate 135 adapted to deflect the es caping chips downwardly at the end of the machine where they can readily drop down into a suitable container.

its the stop bar 82 fits into notches in the frame 59 and tine chips or dust might accumulate beneath the bar in the notches, I prefer to limit its rearward movement in the notches by relatively small adjustable stops 136 in the form of small screws arranged in threaded openings in the frame 59 and adapted to contact at their points with the stop bar 82. The possibility of chips or dust getting between the bar and the points of these small screws is quite remote.

it should be understood that the illustrations shown are merely typical of the many uses of the machine in the production of novel arrangements of type slugs.
